weird g1 hardware issue - G1 General

Ive had my g1 for about half a year now and have never noticed this before, but when its plugged into the wall charger, the little metal screen over the speaker becomes electrically charged and can shock my ear or whatever else i touch to it.
Is this a known issue or is this how my service providor controls my mind?

Instead of phone I would rather check your house electrical wiring for proper grounding

What metal screen...? There's no external metal on the g1 that I can see.

Do you have carpets or rugs? If this is the case, then YOU are getting yourself charged wrt the electrical NEUTRAL and then DISCHARGING through your phone!
THIS IS EXTREMELY DANGEROUS FOR YOUR PHONE!!!! You could FRY it beyond ANY hope of repair. You are literally shocking the thing with HUNDREDS of volts of electrical potential!
I STRONGLY suggest that if something like this is happening, that you get yourself a GROUNDING PAD and DISCHARGE yourself before touching the phone!

Tmobile HD2 heat damage on back

The lower right side of the back of my HD2 looks like it has heat damage. The black finish is bubbling up. I do not believe it was from an external heat source. Is this a known or common problem? Anyone know what is located in the lower right corner of the back side of the phone? I'll snap some pics later.

Pics please.
Only source of heat there I can think of would be the battery while charging. Are you using the stock charger?

There is a video floating around of someone taking the HTC HD2 completely apart, I'll see if I can find the link and possibly you can see exactly what part is located under there.... It was from someone complaining about a cracked screen.
EDIT: found it:

Can you tell me what the brown liquid is? Kinda looks like a coffee spill...
I ask, because to my untrained eye, it looks more like you accidentally sat the phone down in a puddle of a mineral-spirits-based liquid. It looks a lot like what I would expect from paint-thinner or the like.
I wouldn't have thought so until I actually saw the stains on the battery cover as well.
Is there anyone out there with a very hot phone coming back from a charge?
I've left my phone on to charge once, placed it under my pillow. The next morning I got a text and pulled it out to read, the phone was so hot I nearly dropped it, but it did no damage to the bed or the phone. I was able to hold it again after unplugging it for a few moments. Less than 30 seconds in all.
Now I am getting concerned...
Down below on the backside there, under that spot are the heat sinks for the processor and memory

Whoah! If you are 100% sure this is heat damage, return the phone now!
I don't mean tomorrow, I mean right now!
This is a potentially dangerous situation, considering the battery is so close. Remember all the "exploding laptop" issues that were cropping up all over a few years back? Imagine that happening in your pocket or on your dresser at night!
Does the phone still function normally? If it was heat damage to the point it was melting the finish you would expect some chip damage as well. You are not working with some solvent like brake fluids or any type of acids?
When I charge mine it rarely even gets hot. Even under full load with GPS, WIFI etc. it gets warmish but not blistering hot.
Take it back, definately warranty issue unless they can prove it was purely cosmetic - which they would check buy opening up the case - heat damage (interior) would show there.

Looks more like a chemical reaction than a heat reaction, have you had it around any alcohol base liquids like Patron perhaps?
It looks more like the soft-touch plastic came unglued from the case below rather than the case actually melting through and pushing the soft-touch up.
Can you poke it? Does it feel soft (like a bubble of air inside)? Would you mind taking a knife to it and cutting around the boil to see the condition of the case below?
I'll agree with other's here and say that it looks more like external damage.
I've had my HD2 and used it heavily (bluetooth and wifi while charging, screen always on at full bright) and it does get warm. Actually, it's hotter than warm but cooler than hot. Maybe like the bottom of a crappy laptop (or a mac, six of one...). Anyway, it's never frozen or lagged, so I don't think there's any actual damage going on.
I'm going to agree with everyone else who said it looks like a chemical reaction. FWIW, I've seen alcohol-based hand sanitizer do this to the soft touch surface in a car before.

I'm still waiting for the OP to come back and tell us if it might be a chemical burn instead of heat related.
I watched the entire teardown video from an earlier post and from what I could see the heat sink for the processor is located in the center of the mainboard. The only thing directly below the spot in question is the copper/brass antenna. This does not rule out a heat-related cause, but it certainly helps to bring it into question.

From the looks of it, for me it seems externally caused like acetone or the like chemicals. If it were caused by heat as you mentioned, the bubbling would be uniformed for that certain area unlike what we see. And if that where the case, there would have to be a really small circuitry in that area that have risen in temperature at a fast pace to form an almost "branding" like form. Also, you can see the residue of the chemical partially cleaned from that area due to discoloration.
** Sorry didn't mean to be rude.
My G1 use to get about twice as hot as my HD2 ever gets and never had any bubbling or melting. I've had my phone on a car charger stream music over bluetooth and using GPS and it barely gets warm. Your phone would have to get extremely hot to bubble the finish on the phone.

Yeah, My G1 did the same, I always felt like it was going to just melt into a puddle of nothing with how hot it was getting. Check your battery on your G1, mine has swollen from the heat.. Haha, thank god I have the HD2 now!

Odd Problem

I was done texting someone, so I put my phone down on my desk. I did it... less gently then usual, so it landed with a little "thud". It turned itself off. It turned back on fine, but is this normal?
On the battery cover there is a little hook to hold the center on securely, make sue it is still there and not broken/worn down. The pre had that problem when it first came out, an easy fix is to put a thin piece of foam or paper between the battery cover and the battery to ensure you dont have a momentary loss in power due to large accelerations.

Mmm-hmm, the hook is still there.
I have noticed that the cover will pop off when dropped(I have unintentionally tested to the extreme of my phone flying a good 10-20 feet in the air onto concrete). It could be possible that it moved just enough that the hook didn't hold.
Hopefully, you don't have a bad solder joint in there, which that issue could also be indicative of...
Good point. But really, 20 feet? That seems a bit much. The most I've dropped my Hero is about 5 feet from my face.

I was walking and slipped on some ice and ended up throwing it... I was on the phone at the time too.
I would try the folded paper/foam under the battery cover first. Remember, there is the high possibility that you will get a replacement with 2.1, but if you are going to get one with 1.5 the time would be now. If you have a Q-Tip and rubbing alcohol, it probably wouldn't hurt to clean the connection to the battery. Make sure none of the tabs all the way around your battery cover are broken, cause they may just be able to give you a new one of those.

None of the battery tabs are broken, cleaned the connections with some Isopropyl I had lying around, and put a peice of paper between the battery and the cover, without touching the camera or the hook that holds the cover on. If it keeps happening, I'll cross my fingers and go in for a replacement. Thanks for your help
EDIT: Just did a test by dropping it the same way I did earlier (about 2 inches off my desk) and it stayed on fine.

Glad it seems to have worked for you, that's how they fixed the early versions of the Pre was to just put this little sticky piece of foam to hold the battery in place.

What are the metal pins that connect to the battery cover?

Ever notice how there are two metal pins on the back that make contact with the metal cover? Why did HTC put them in there?
Also would one be able to hardwire the antenna too these points so that the metal battery cover can be used as an extended antenna?

They are probably there to cushion the force of the back place being clicked on.

Not a chance, have you ever pulled a HD2 apart? I severely doubt it is a wise idea. Hardware modding of a phone is a fools game.
Is it to dissipate heat?
It's for the car GPS kit.

Not the 3 pins, the 2 balls on either side of the phone.
Is it really for a GPS kit? Maybe that concept kit that HTC never came out with? But what would they do it can't be for power.
Sent from my HTC HD2 using XDA App
This comes up every month or so, and i agree with Kalavere in that they are there to keep the back plate snug. They are spring loaded, so the plate wont get wobbly with extended clicking on/off. Since the reset button is under the back panel, it seems reasonable that HTC would expect the plate to be removed fairly often.
I also think it plausible that they are earthing points for the antenna, but i think that a little less unlikely.
Not sure exactly what they are for but I am positive they are not there to keep the backplate snug.
They are some kind of a contact point. The metal cover bridges the connection. You will notice that the cover is clean where the points contact.
Never seen the car kit but that is a possibility. I doubt very much that they have anything to do with the antenna. My guess is that they might simply be a ground shield.
I had the same question, I rung up the HTC support here and they told me that even they are not sure, but they did mention that on the inside, it's linked to the antenna for the GPS. Don't know what they mean by that but I guess, it's either an earth (since, if you notice, the area where the nobs rest has the paint scrapped off), or the whole back plate is an antenna. I tried to insulate it, no diff to operations of the GPS or Phone.. *shrug*

Hardware Modifications

Well I finally have everything set up the way I like it internally. But of course I can't stop tinkering just because I'm done with my software. So now I am thinking about doing so external modifications to my device.
I know this will void my warranty. Not concerned about that. It its voided already due to a few unfortunate drops and a lost battle with some moisture.
I saw one modification to the case already. Someone had sanded all of the black paint off of that case to expose the red plastic. Think this might be my first step. Something I was really anxious to try was changing out the leds for the bottom for keys (home/menu/back/search.) Need some feedback on this though. Has anyone tried it yet? Questions? Comments? Concerns? Anything at all.

Yep. this guy did it: http://forum.xda-developers.com/showthread.php?t=696526
i'd be interested to see how the sanded battery cover would come out. how do you plan on getting it smooth and refined looking? higher-grit paper?

Thanks for the link. Couldn't seem to find anything on it.
I am not sure if I am going to do that battery cover. Just the part of the case between the main body and the battery cover. That thin flat black strip. I don't know if the battery cover is red underneath.
And you are exactly correct. Knock off the paint with a lower grit. Then polish it up with some 1000 or 2000 grit. Maybe a little bit of wet sanding.

My evo has the red trim now (knife to scrape, sandpaper to polish), and induction charging. My warranty was void soon after I got it thanks to taking it apart to solder.

There is a thread floating around about it.
The led changes are very easy. Unfortunately my hands have always shaken too much for this type of soldering though. If only i could teach my wife such things....

That mod with the battery pins and contacts from an old phone instead of wire would give a very OEM look.
not so sure about replacing the leds under the bottons, but i'd like to change the charging/notification light. think i remember seeing it changed to blue/white to good effect.

S6 is vibrating itself off the wireless charging pad.

A bit of a random one that falls under the "I crap you not" category, but it seems the combination of slippery glass back + a wireless charger (non-Samsung brand) that has a high pitch whine seems to be just enough to cause the phone to slowly rotate until it completely falls off the charger after about 5 minutes.
Just throwing it out there in case I'm not the only one. I'm going to be putting a Ringke slim case on it in a couple days like I did with the S3, S4, and S5 which will solve the problem.

The phone's vibrator isn't what's vibrating. My guess is it's inductor coil whine that's causing just enough vibration to rotate the phone off the pad (wiki has a page called Coil noise)
Oh wow, that's... kind of awesome, in the worst way possible. I'll say this: I have no issues whatsoever with my Nokia Qi chargers, the D900s I believe? The plates that AT&T sold for the Lumia 920, and they blew out for $5 each a while back. Awesome, awesome chargers.

This. Just a thin rubber film should suffice.
By the way, have anybody tried to use wireless charging with the S6 wrapped in a protective case? I read about materials and wireless charging and I read even 1 cm of plastic barrier should not be a problem, but just wanted to make sure if somebody has tried it already.

Plastic / rubber should be transparent to wireless charging, and my S6 connects to the pad with even a 1/4" air gap.

It seams that it really happens, very weird though.

Wow you have a good eye, but yeah at 16:10 you can see the USB port on the phone starts rotating away from the USB cord.
At the cost of a scratch to the bottom left of my S6 I can confirm that it will vibrate off of the charger even if it is placed in the centre of it. Its disappointing that Samsung hasn't tested the phone's wireless charging and picked up on this. I've contacted Samsung to see if anything can be done about it and I'll let you know if/when I get a reply.
